- Brain in a vat (Wikipedia)
In philosophy, the brain in a vat (BIV) is a scenario used in a variety of thought experiments intended to draw out certain features of human conceptions of knowledge, reality, truth, mind, consciousness, and meaning. It is a modernized version of René Descartes’s evil demon thought experiment, originated by Gilbert Harman. Found in many science fiction stories, it outlines a scenario in which a mad scientist, machine, or other entity might remove a person’s brain from the body, suspend it in a vat of life-sustaining liquid, and connect its neurons by wires to a supercomputer that would provide it with electrical impulses identical to those a brain normally receives. According to such stories, the computer would then be simulating reality (including appropriate responses to the brain’s own output) and the “disembodied” brain would continue to have perfectly normal conscious experiences, such as those of a person with an embodied brain, without these being related to objects or events in the real world.
- Populism (Wikipedia)
Populism is a range of political stances that emphasize the idea of “the people” and often juxtapose this group with “the elite”. It is frequently associated with anti-establishment and anti-political sentiment. The term developed in the late 19th century and has been applied to various politicians, parties and movements since that time, often as a pejorative. Within political science and other social sciences, several different definitions of populism have been employed, with some scholars proposing that the term be rejected altogether.
